Application filed December it known that i, HENRY l7. ArLwAnn, a citizen. of the United States, and resident of the l. orough of Brooklyn, in the county of Kings and State of New York, have invented cediain new and useful improve ments ll :ttrical Signaling Apparatus, of which the following is a specification.

This in J ntion re ates to electrically controlled signaling apparatus of ti at class in which an indicating member of a. receiving instrument is caused to move to any one of a number of definite positions in response to the niovenie it of a circuit-closing and circuit-opening member of a transmitting in strument; and the object of the invention 'is to provide a simple and reliable apparatus of this class.

The invention consists of a receiving instrument having a movable ii'ldicatino; member controlled by a crank-sliait that is adaptcd to he rotated in a step-hy-step manner by connecting arms, actuated by electromagncts, and means for energizing and deenergizing the said electro-inagnets The invention further consists of means at both the receiving and transmitting sta- I in the accom anying diagrai'mnatic drawi mg, which shows a receiving instrument A,

a transmitting instrument B and the plan of wiring connecting said instruments, similar reference characters denote similar parts. 5

Referring to the receiving instrument ii, the numeral 1 indicates a dial, and 2 denotes an indexing hand adapted to he moved. to a series of definite positions on the hue of said dial by the axial. movement of the shaft- 3, which is actuated by a gear-wheel i that meshes with a gear-wheel 5. The said gear-wheel 5 is fixed 0n the shaft 6, on which is also fixed the disk '7, having a crank-pin 8 to which is pivotally connected one end of each of the connecting arms 9, and to the other end of each. of the said arms is pivotally connected a niagnetizable core 10 of an electro-magnet 11.

For the purpose of illustation, I have shown magnets of the solenoid type, and it will be seen that when any one of these magnets is energized, its core will seek a posi tion that will locate the crank-pin at that point in its path of travel nearest the said magnet, and that the said core will contact with, and close one of the switches 12 for a nnpose that will he hereii after explained. The imnieral 13 indicates he source of current, one pole of which is connected to an annular plate letoi the transn'iitting instrumenthrough the wire 15, and the other pole to a return wire 16, common to all the magnets. The rid transmitting insiumeut is tn'ovided with switch-arm 1'7, pivot-ally secured at one of its ends, in constant contact with the annular plate lat and adapted to he brought into successive contact vith pluralitv of plates 18 corresponding in number to that oi? the signals which may be indicated on -the dial ot the receiving instrument. 'i lose p ates are connected by the line wires 19, 2t) and 2.1 to the magnets 11 of the receiving instrument, their order of connection heing such, that as the switch-arm it? is moved, the circuit will he closed and opened on the said wires successively.

'the receiving instrument and the transmitting instrument are each prmided with a device or the purpose of detecting errors in the transmission of the signals, which, as shown, consists of a disk attached to an arm 2'23, (23) which is moved by the magnet t, when the. latter energized, and, these magnets are connected to each other my the line wire and 26, they any one to the source ot' current by the wire will be energized by the closing of of the switches 12, hetero referred to, oil? the receiving instrument, ther indicating at both the receiving and transmitting stations that; the receiving instrntnent has esponded to the movement of the switch-arm ot the tra sinitting instrument.

is each of the magnets 11 ot the receivii'ig instrnmentcapable of cauiing the shaft 6 make one-third c-t' its rotation, and, as this partial rotation ot the shaft may be converted, arin into deby .neans oil ,7 siren. part. of a revolution of the indexing hand 2, itis obvious that any desired number of signals may le transmitted without increasing the numher ot line wires or the number of crank-shitiii-actuating magnets, as the successive closing and opening of the circuit on the three line wires 19, 20 and 21, and the consequent successive e1 ergizing ol the three shaii'hactuating magnets 11, may be repeated indefinitely by connecting a plurality ot the contact plates 18, of the transmitting instrument to each of the said line llt" - a multiple of the wires. In the event that the number of the contact plates 18 is a multiple of the number of the magnets 11, the switch-arm 1'7, may if desired, be moved continuously in one direction; but when, as shown in the drawing, the number of the said contact plates is not number of the said magnets, it will be seen that two adjacent plates will be connected to the same line wire, malting it necessary to provide a stop QT for the switch-arm, between said plates.

It will be noted from the foregoing description that the magnets 11 ot the receiving instrument and the crank-shaft thereby actuated, constitute, what is in effect, a motor, capable of moving an indicating hand in a step-by-step manner in either direction in synchronism with the switch-arm l? of the transmitting instrument, and it is thought that the operation of the apparatus will be apparent to those skilled in the art.

I claim as my invention operated by the cores of said electro-mag nets.

2. in signaling apparatus of the character described, in combination, a receiving instrument having a plurality of electro-mag nets, and a crank-shaft arranged to be retated in a step-by-step manner by said magnets, an indicating member adapted to be actuated by said crank-shaft, a transmitting instrument adapted to energize and deener gize the magnets of said receiving instrument successively, and auxiliary signaling means for indicating each step of the said crank-shaft at both the receiving and transmitting instruments, operated by the said electro-magnets.

In signaling apparatus of the character described, a receiving instrument having a plurality of reciprocally movable members, electro-magnetic means for moving said members, a c ank-shaft arranged to be rol. In signaling apparatus of the character shaft, and auxiliary signaling means condescribed, in combination. a receiving instrument having a plurality of electro-magi nets and a crank-shaft arranged to be parf tially rotated by each of said magnets, means for energizing said magnets succesnaling means for indicating each partial rotation of said shaft, controlled by switches tated by said members, an indicating member arranged to be moved by and cranktrolled by switches operated by said reciprocally movable members.
